ORE SEPARATING AND CONCENTRATING MACHINE.

To all whom t may concern:

Be it known that we, WILLIAM P. CLIF- FORD and WILLIAM W. RANK'IN, citizens of the United-States, residing at' Iconium, Vin the county of Appanoose and State of Iowa,

spectively, have invented new and useful Improvements in Ore Separating and Concentratin Machines of which the following The invention'relates to improvements inore se arating and concentratin machines; and t einvention belon s to t at type or class of machinesin Whic the valuable particles of the crushed or,reduced ore are concentrated into as small a' bulk asis economically advantageous by the fall of the parti- This concentration of articles is generally brought about by the all of the particles in'water; but, las is well known, by this process the concentration depends upon the difference in specific gravity of the valuable orey and the waste vein stone or rock. l

The smaller particles of ore are separated by a variety of machines. The action of man of them is based upon the behavior of particles carried down an inclined lane byfa thin stream of Water. If the adient of the plane and the strength of the t 'n current are ro erly arranged, the denser particles will he eposited and the` s eciically lighter ones washed away, althoug they may beequalfalling if allowed to settle in deep water. v

The paramount object of this Invention is to overcome many of the diliiculties expe'- rienced in lconcentrating in Water, and to produce a generally'improved ore separatin and concentrating machine, which will be simple in construction, cheap of manufacture, and efficient in use. 4

lAnother object of the invention is to produce an improved ore separating and con-` centrating machine for the treatment of very line ores and practically lsaving all ine ores and mineraldust heretofore Wasted away in treating by the water process, or by improper air blasts, or air currents, improperly applied.'

With these ends in view, the inventionA Specification of Letters Patent.

. Application filed March 2,1906. Serial No. 303,750.

consists inthe novel construction, arrangement and combination of parts hereinafter described, Aillustrated in the accompanying Patented May 14, 1907.vv

drawings, and particularly pointed out in the appended claims.

v Referringto' the accompanying drawings, forming a part of this specification, Figure 1 is a horizontal sectional -view of the improved ore separating and concentrating machine with aportion ofits side wall, adjacent to the fan, left intact in order that the construction may be more readily understood. Fig. 2, a transverse sectional view taken throuh line 2-2 of Fig. 1. Fig. 3, a view, partly in section, of the front end of the Inachine. -Fi 4, a perspective view of the corrugated sha erf plate.. Fig. 5, a detailed perspective view of the base plate upon which the corrugated shaker-*plate 'is slidably mounted.

Similar numerals and letters of reference designate like parts throughout all the iigures of the drawings.

- Referring now to the drawings,`theiframe of the machine consists of suitable base beams and uprights l, to which are secured the side and end walls 2, of the machine.

The machineis known as a dry Worker,

in which'the various articles of ore are concentratd by means o air blasts and currents roduced throughv the medium of a suctionan 3, suitably mounted in a casing '4, lo-

cated at the rear or fan end of the machine.

"The ore enters the machine' from the crusher through a chute 5, located at the front. or re- "ceiving portion of the machine, wherel it falls into a hopper 6. j

The ores areI concentrated and separated and carried through the machine through the medium of air currents, and, in the present instance, a air of inclined corrugated shakerplates 7, sidably mounted upon a pair of su porting-boards or'plates 8, provided with side walls or-boards 9, and said supporting boards or plates are adjustably mounted and, secured within' the frame of the machine by means of adjusting bolts and thumb nuts 10, secured to standards 11, of the machine.

The supporting-boards or plates 8, are in-` clined laterall as w`ell as longitudinall and these inclinations may be changed as esired to provide for various ores and the desired concentrationsthereof by means of the said adjusting bolts and nuts 10. A' frame 12, carrying a glass plate I3, is adjustably secured above the corrugatedshaker-plates,7,l

by means of curved4 supporting-straps .14,

. corrugate' -shaker-plates 7, slidably mountto observe the behavior of the ores upon the shaker-plate 7.

The shaker-plates 7, are slidably mounted on the supporting boards or plates 8, andl are moved to and fro thereon by means of a pair of connecting-rods 15a, secured at their rear ends in any suitable and convenient manner, and said connecting-rods 15?, are secured to the upper and lower ends of a pair of verticallyarranged operating-bars 16, mounted on a rock-shaft 17, secured in suitable bearings 18, secured to the front end of the machina The rock-shaft 17, with the vertically-arranged operating-bars 16, carried thereb ,i

areoperate'd by means of a pair of cran arms 19, adapted to be oscillated byl means of a pair of eccentric rodsor bars 20, operated b a pair of eccentricblocks 21, mounted on tlire revoluble shaft 22. The shaft- 22, is mounted in suitable -bearings23, of the machine, and is provided at its end with a pulley 24, operated by means of a belting 25, passing over the same and 'over a ulley 26,

secured to the end of the shaft of t e suctionV fan 3', at therear or fan end of the machine.

The sup orting-boards or plates 8, and the ed above, being inclined laterally toI the right, as well as incline'd longitudinally toward the fan end of the machine, as the material enters at-the u per left hand corners or portions of the shaler-plates 7, it will be drawn across and over the shaker-plates 7, by the force of the air currents, gravit and .the inclination and vibration of the s akerlates, whereby the pure ore will be drawn orwardly and laterally along the shaker- -and 5), in one side of the shaker-plates 7, and

supporting-boards or plates 8, and below upon a chute 28 inclined longitudinally, and laterally to the left, and the finished ore carried thereby is conveyed and deposited by means of thetrou h portion 29, formed `with said chute 28, an deposited as finished ore. Asecond chute'30, is mounted beneath the opening or slot 27, and is adapted to receive the less finished ore from the sides of the shaker-:plates above, and to convey the material thus received through the medium of a trough'3i1, formed integral therewith, to the upperaleft hand cornerA of the succeeding shaker-plate, for further treatment, or should this chute be beneath the last shaker-plate of Ithe less finished ores from t a series, then to a convenient lace of deposit. where it may be taken up and) again t1-cated, if desired. A dividing valve 32, is slidably mounted in the chute 30, beneath the opening or slot 27, and is adapted to he moved longitudinally to meet` the requirei'uents of various ores and the desired concentrations thereof.

A transverse opening or slot 33, is formed at one end of the sup orting-board or plate 8', and is provided witli the transverse chute 34, having its receiving end adapted to receive the finished tailings from the lower right hand corner of the shakerlates and convey thc same to some suitahlie place of deposit. A second chute 35, is arranged above the chute 34, and is adapted to receive ic end of the shaker-plate, and is provided at its lower end with a trough 36, emptying into the trough 31, of the chute 32, whence it is conveyed through the trough 3l, to theu ,per left hand corner of the succeeding sha erlate for further treatment, or should it be t e last in the series, then to some suitable lace of deposit, wher'e it may be again ta en up and retreated, if found necessary or desirable. Asliding valve 37, is slidably mounted in the chute 34, and is adapted to be moved along the opening 33, to provide for the various ores and for varying the concentrations thereof. It will be understood that any number of shaker-plates with the necessary connections may be arranged in a series in one machine, if found necessary or desirable.

A trunk 38, is mounted, in the present instance, in front of the first shaker-plate and itsnecessary connections and communicates with the air passage above the shaker-plate by means of the au' assage 39, at the rear of the trunk 38, anrfsaid trunk communicates with the suction-fan through the medium of the air passa e4 40, trunk 4l, and valve 42. A dividing oard or partition 43, is mounted transversely in the trunk 38, and pivotally attachedat its lower end, intermediate valves 44, and 45, formed at the lower end of said trunk 38. The dividing-board or partitions 43, is operated, in the present instance, by means of an operating-rod 46,

secured to the free end thereof and extending i to the rear end of the machine. The tailings deposited through the valve 44, may be returned fory further treatment, if desired, while the valve 45, is adapted todeposit finished tailings. An air passage 46, provided with the valve 47, communicates with the suction-fan and with the air passage above the second or succeeding shakerlate, as the parts are arranged in the maciiine, herein shown and described.

When the machine is in operation, it will be observed that the finer and less valuable particles of ore will he drawn by the force of the air blasts or currents through the air pas- IIO adapted yto catch and receive many minerali lusts heretofore wasted by the water process,

such 'as zinc, yellow and red ocher, etc.

As theair currents are drawn along and across the corrugated shaker-plates, andare vibrated, the lighter particles of ore are agi-lP tatcd and worked to the top and are drawn by the air currents over and across thecorrugations, `while the heavierl particles of ore are gradually worked down'mto the lowest' portions of the channels or corrugations and down towardV the lower or discharge ends of theV same. The corrugated shaker plates are' slightly inclined toward the corner diagonally opposite the cornerl where thematerial enters.

' The purer and finer grades of ore will therefore be found near the lower ends ofthe first corrugations,iand the material with ,little or no ore in it will be found at the upper ends of thelast corrugations. lThe material or ore from these points tends to grow less pure in the one instance, and richer and more pure in ore in the other instance, as it moves toward the corner diagonally opposite the corner' of intake, and hence by the use of the sliding valves 32 and 37, we may provide for the various ores and the desired concentrations thereof. l

Having thus described the yvarious parts of our invention, its operation and advantages will be readily understood by those skilled in the artto wlnch it appertains. l

Without having attempted to set forth all the forms in which it may be made or all the modes of its use, we declare that what we claim as our inventiomand desire. to secure by Letters Patent, isl V1.
